Freeze Cannon

The Freeze Cannon is an invention of Mr. Freeze. A year after his accident, he initiated a revenge scheme against Ferris Boyle and GothCorp, his former employers. Various components were stolen from GothCorp facilities around Gotham City and assembled into a giant version of the Freeze Gun. The Cannon was to be used to freeze the building used for a ceremony to award Boyle. However, Batman arrived and sabotaged it. After Freeze was arrested, the Cannon was most likely confiscated by the Gotham City Police Department and later returned to GothCorp.
